A recent publication by the U.S. Army Center of Military History presents an operational-level narrative of how the U.S. Army formed, trained, deployed, and employed its forces in Afghanistan from October 2001 to December 2014. Modern War in an Ancient Land: The United States Army in Afghanistan, 2001 – 2014 is a two volume set by the Operation Enduring Freedom Study Group.
These two publications were the result of an extensive research program that conducted oral history interviews with dozens of key military and civilian leaders. These volumes contain a total of fifty maps, a wide range of campaign photography and artwork, and volume-specific indexes. The first volume (436 pages) covers the 2001 to 2005 time frame while the second volume (580 pages) covers the 2005 to 2014 time frame.
Modern War in an Ancient Land, U.S. Army Center of Military History, 2021 is available online as a PDF document.
